Application filed October 17, 1925. Serial No. 63,069.

a rotatable support having a circular series.

of mechanisms thereon for forming and clamping the bands of paste board boxes in order to enable the ordinary tops or bottoms as the case may be, to be secured thereto, and then, the extension tops or bottoms; said support having an intermittent rotary movement, thereby permitting an attendant to accomplish the first stage of the work on each of a series of boxes in successive order, while the support is at rest, the second stage of the work commencing with the first box of the series when the support has made a complete rotation.

Further to provide a circular table having an intermittent rotary movement and provided with an endless series of mechanisms for forming the band portions of paste board boxes into any one of a variety of shapes, and clamping said band portions while the bottoms or tops, as the case may be, and then the extensions are secured thereto by an attendant during one complete rotation of the table; the extension bottoms or tops being adhesively secured to the original bottoms or tops and clamped thereon, the boxes being removed in successive order upon the next rotation of the table.

Further, to provide a rotary series of band forming and clan'iping devices, each of which comprises a form of any desired "outline and manually operated (lies which conform to the shape of the form and which are adapted to clamp a band around said form and hold said band while the usual bottom or top is secured thereto, and while an extension bottom or top is secured to the usual bottom or top, means being provided i'or clamping said extension bottom or top 111 place, and holding the same until the until the adhesive material is set.

These and other objects which will here inafter appear, are accomplished by the pparatus illustrated in the accompinying drawings in which:

last box oi? the series is completed, all the The muneral 1, indicates asupporting strum lure which is made up of connected rec tangularside, end and top frames, a platform 2, being supported on the lower members of opposite side frames, as shown in Fig. 2. Upon the platform 2, is secured -a metal base plate 3, having a bearing socket 4 near its inner end vertical bracket-s or uprights 5 on its outer end. and a vertical Lnpright 6 intermediate of its ends. To the uprights 5 and 6 is bolted a gear housing; con prising a horizontal hollow cylindrical part- 7,*having a hat hollow extension h to which is bolted a hollow sein-i-cimular cap 9, the extension 8 and the cap 9 having registerinp,- bolt flanges 10 which are eonneetet by bolts ll shown, in Fig. 3. Axial hubs 12 and 133 are formed in opposite sides of the lat part of the housing; one half of each hub being" "formed on the extension 8, and the other half on the cap The cylindrical part T of the l-iousi-ng is formed with a l-iorizontal projection l-lhaving dependin lugs 15 which are bolted to the uprights and the cap 9 is formed with depein'li'ng lug l6 wl'iich is bolted to the uproht (5 as ch a rly shown in Fig. 4-, a short shaft 17 is mounted in the hubs 12 and i3 and on the lower portion of this shaft is keyed or otherwise secured, a worm gear it which is en zlosed by the exile aion 8 and its cap 9 and this a1: meshes with a worn-i pinion 19 in the cylindrical hous' which pinion is secured upon a shaft 20 which is jm'irnaled in cups "7 which are bolted to the ends of the cylinder 7.

The shaft- 2t) extends beyond one end ot" the cylinder 7 and its end port-ion is mounted in a bearing 21 which bolted "to the adjacent side of the supporting structure l. A stepped belt wheel 22 is secured upon the shaft- 20 and this wheel connected by a belt 23, with a stepped pu-l-le which is secured upon a shaft 25 which is inormted in bearings secured to the opposite side of structure 1 from the shatt 'll'ie shaft 253 has a bet wheel 26 secured upon one 0' d thueot, which is connected by a belt 2? with a small pulley 28 on the shalt of an clot-trio motor 29 which is bolted to the platl'tn'ln 2.

Thus. power from the motor 29 is comuiunicated by the belt 27 to the wheel 26, the sl-iatt and stepped pulle v Z-land thence by belt 93 to wheel 22 on the shaft fil and thence by worm pin-ion 1 and worm gear to the shaft 1T.

l'pon the upper portion of the shalt i7 is secured 'a disk or wheel "30 having a hub which rests on the hub 12 of the gear llUilH- ing F A). The disk 30 has formed lhe'i'ci-m or secured thereto a short. radial arm or lug 81 which extends slightly beyond the ciretm'iterential edge of the disk, the under side of the lug being slightly above the Upper t1}? llSk, at 916th? lIO ill l3 I Fig". -;t.

and upon -each"rot atio11 of the disk 30, the

pin 32 enters one of the slots 33 and turns the disk 3%, one sixth of a complete rotation before the pin 32 passes out of this t; the n xt succeeding slot 32:; being in position to receive the pin when it intersects the circular pat lrdescribed by the open end of said The purpose of the intermittent rotatim ot the disk 34L will hcreiiurtter appear. The circu-n-rterential paths o t the disks 30 and 31- intersect or overlap each other, as will be seen by rclcrez-ice in l 3, and as both disks are on "the same pla c this arrangementis provided for by inwardlv curving the edge iioi'tioi is oi" hie disks at between each two slots 3 in arcs 3G hating the same radius as the circumference of the disk 30, so that the edge of the disk 30 will ride successively in the arcs as the disk S t is rotated by the disk Ill). The edge -alrtion 57 of the disk 34;, on earl side of the slots 33, represent the diameter of the disk Ell and these i of the disks intersect or overlap the circun'iterential path of the disk '30 as each slot 33 approaches and passes a line drawn througl-i the axial centers of the disks, and therefore, the edge of the disk 1-30 is inward- 1y curved at 238 on an arc whose center on a line which passes through the axial centers of the disk 39 and pin 32; thus the edge portion of the disk 34, having the great-est diameter ride in the curve 38 on each. partial rotation of the disk 34- by disk 30.

Upon the top ot the support 1 is secured a pair of parallel. bars 39 upon which rests a circular metal plate 40 which is botcd to said bars and is pr Yided with an areal hole through which the shaft passes. The plate ll) is provided with a circular ball race which is supplied with balls il upon which rests a plate also having a hal race. The plate 42 is integrally connected by a hub 43, and ribs ll witl'i a h 'gcr plate to which constitutes the base plate for a -ircular table, to be presently described and the shaft 3 5 extends through an axial opening in the hub 413' and asu-itable distance above the base plate for a purpose which will later appear- A set screw as in the hub i is screwed against the shaft 3.) and thus rigidly secures the base plate and its plate 42 to the said; sh'a ft 35.

To the top face of the base plate are belte Of r dial b r P efe abl channel bars and six in number as shown in Fig. 1, and the outer ends of these channel bars are connected by a circular angle bar 48, as shown in Figures 1 and 7, the circular bar 48 being about seven feet in'diameter.

The radial bars 47 are further connected by segmental angle bars 49 which are concentric with the circular bar l8 and a suit able distance from the same, and upon the horizontal members of the bars 48 and 49 are secured segu'iental table sections 50 in the form of wooden blocks which together make up a ring-like table which supports the box forming and clamping mechanisms which will now be described.

There are preferably six of these mcch anisms and as they are identical in construction a description of one will suffice. Upon the table sections 50, on each side of'each of the radial channel bars 4:7 are secured tran \OISQ wooden strips 51 and 52, the strips of each pair being in the same direct line but separated by a space as shown, and upon each pair of strips is secured a guide rail 53, said guide rails being parallel as shown. The outer edges of the guide rails are beveled as shown in Fig. 6, and upon these beveled edges are slid-ably mounted the side bars 5% and of two frames A and B which are movable back and forth with respect to each other, and which together form a rectangular frame.

The side bars 54 of the frameA are connected at their rear ends bya wooden bar 54 and at their forward ends by a metal bar 56 which is secured to the under edges of the bars 54; and lies beneath the guide rails 53. The rear ends of the side bars 55 of the frame B are connected by a metal bar 57 which also lies beneath the guide rails 53 and the intermediate portions of these two bars are offset from the end portions so as to leave a space of considerable width between the middle portions: of the two bars when the frames are in closed position to permit the lower portion of a box removing plunger to extend down between them, as will herein after appear.

The front ends of the side bars 55 of the frame B are connected by a wooden bar 55, and the inner faces of the two side bars 54% of the frame A and the two side bars 55 of the frame F are beveled and undercut to engage the correspondingly beveled edges of the guide rails 53 and by this arrangement the frames A and 1% are limited to a horizontal sliding movement on the guide rails 53.

The inner ends of the strips-or blocks 5.1. and 52 form stops which define the outward movements of the frames A and B. the bar 56 of the frame A being engaged by the blocks 51 while the bars 57 of the frame B is engaged by the blocks 52.

The frames are slid toward and away from each. other n the following manner A contraction coil spring 58 is secured at its lnner end to the bar 56 and at its outer end to' the channel bar 47, and a similar coil spring 59 is secured at its inner end to the bar 57 and at its outer end to the channel bar 27, and these springs tend to draw the frames apart or away from each other. A bracket 60 is secured upon the right hand end of the cross bar 55 oft'he frame B, and abracket 61 is secured to-the under side of this bar and centrally of its length. A rod 62 is rotatably supported in the brackets 60 and 61 and the innerend of this rod terminates in a short right angled portion or lever arm 63 to which one end of a rod 6i is pivotally attached. This rod extends rearward andi through and beyond an alnlti'nent plate 65 which is secured upon the cross bar 5% of the frame A and its free end is threaded and provided with a nut66. A coil spring 67 surrounds this rod between the abutment plate 65 and the nut 66, and this nut may be adjusted to vary the tension on the spring, the position of the nut being maintained by a jam nut, as shown in Fig. 5. Upon the outer end portion of the rod 62 is secured an operating handle 68 which inclines in 'a direction substantially opposite that of the lever arm 63 on the inner end of the said rod 62, so that when the handle is turned to point inward, the lever arm 63 points outward, as clearly shown in Fig; 7.

In this position of the lever arm 63, the rod 64: is drawnupon, the coil spring 67 is under compression and the frames 'A'and B are locked in closed relation. The manner in which the frames are moved from an open position, as shown by the three clamping units on the right side of Fig. 1; to a closed position, as shown by the three units on the left side of Fig. 1, .is as follows :As the operating handle 68 is swung forward, the rod 62 is thereby turned, and the lever arm 63 on the end of this rod draws on the rod 64 and the nut 66 is forced. against the spring 67,which is thereby forcedagainst the abutment plate 65, this exerting an inward pull on the'frame A. which is held at the limit of its outward movement by its spring 58. The frame 1% is also held at the limit of its outward position by its spring 59, but as the handle 68', is moved forward the lever arm 63 fulcruniis on the end of the rod 64:, and further moven'ientof the handle forces the frame B inward until it is stopped by the adjacent ends of the guide rails 53; the bearings 60 and 61 for the rod 62, then become a fulcrum for the lever arm 63 which then draws the rod 6-1 forward. thereby forcing its spring 67 againstthe abutment plate 65, and thus sliding the frame A inward until it is stopped by the adjacent ends of the guide rails 53.

the he spring 6? is compressed between the abutment and the nut 66 on the rod 6st, and serves to lock the frames in closed position as the end of the lever arm turns to the position when the line of pull on the rod 64 is shifted from below to above the center of the operating rod (32, when the lever arm 63 engages the under side of the cross bar 55 of the frame B and is held there-against by the pressure of the spring 67 on the nut 66. To open the frames, or slide them apart, the handle 68 is svmng in the opposite direction, or outwaro and the instant the outer end of the lever arm (53, passes below the center of the operating rod 62, the pressure on the spring 6'? is released and the frame A is first slid outward under the action of its spring 58, followed by the frame l3 under the action of its spring 59.

.A board 69 is placed between the guide rails 53 and is secured to blocks 51 and 52. Upon this board is secured by screws, a block 70 which may be of any desired shape such as round, square, hexagonal, heart-shaped, etc, the block in the present instance being heart-shaped. This block determines the shape of box and therefore it is removably secured to the board 69, so that the other blocks may be employed for any one of a variety of styles of boxes.

Cooperating with (no block 70 a pair of formers or dies, which taken together are of the same shape or outline as the block, and one of these dies 71 is removably secured to the frame A. and the other the 72 is removably secured to the frame B. Thus, when the frame is open, the dies are moved away from the block 70 and when the frame is closed, the dies engage the block, or rather the box band which surrounds the said block, and presses the band against the block, at all points, as will be later more fully described. The blocks 70 is formed with a circular aperture 73, which registers with a circular aperture 74 in the boards 69, these apertures accommodating a plunger 75 for removing a completed box from the block. The plunger '55 is in the form of a cylindrical wooden body provided with a cap 76 of the same dian'ieter which is secured thereto. A. spherical recess 77 is formed half in the cap and halt in the body, and an axial hole 78 of less diameter than the spherical recess is bored through the lJOC y and intersects the half part of the spherical recess 77 therein. Before the cap 76 is secured to the plunger a stem 79 is passed down through the axial hole 78, and this stem has a'ball 80 on its upper end which its loosely in the spherical recess 77, when the cap is secured to the plunger. The lower end of the stem 79 is screwed into a sleeve 81 in the lower end of which is secured a short rod 82having a portion bent at right angles thereto, the end of which terminates in a ball 83 which enters a socket in the head of a bolt 84 which is secured to one end of a lever 85. The lever 85, is pivotally secured, intermediate of its length to a bracket 86 which is bolted to the bottom of the adjacent radial channel bar l7 which extends beneath the slidable frames A and 13, as shown in the drawings.

The other end portion of the lever is provided with a slot S7. A horizontal rod 88 passes through a hole in the left hand block 52 and its inner end portion is bent at right angles as shown at. $9 to form a lever arm, and a bolt 90 passes through the end of this lever arm and loosely through the slot 87 in the lever The outer end of the rod 88 is provided witha vertically disposed handle 91 which when drawn upon, turns the rod 88 the lever end 89 of which rocks the lever 85 thereby raising the plunger T5 to remove a finished box from the block 70, as will hereinafter appear.

Upon the cap of the plunger is secured a thin metal plate 92, which is slightly smaller than the block 70 but of the same shape or outline and this plate rests in a recess in the top of the block so as to be flush with the top surface of the block. This plate is of such size that it bears against the greater portion of a box bottom or top when the plunger is operated, thus facilitating the removal of the box or cover as the arse may be, from the block 70.

A vertical depending guide rod 93 is seoured to the plate 92 and this rod extends down loosely through a hole in the block 70 and the board 69 and prevents the plunger from turning on the ball 77, which supports it. The ball and socket connection between the plunger and the rod 79, and between the angle rod 82 and the lever 85, permits an automatic adjustment of the plunger on its axis, with respect 'to the box bottom, thereby permitting the plate 82 to bear squarely against the box bottom and thus remove the box from the block by a direct vertical push, by which binding of the box hand upon the block is prevented.

A spring M is secured at one end to the bottom of channel bar lT, and at its other end to the forward pmrtien of the rock lever 85, and this spring normally holds the plunger in an inoperative position. or so that the plate 92 rests in the recess in the top of the block 70.

On the left side of each frame A-ll is a vertical standard 95 in the form of a section of tubing which is secured at its lower end in the hub portion of a circular plate 9a; which is secured to the table, the standard being close to the frame and in line with the inner ends of the frame members when they are in closed position. A tube or sleeve 97 of less length than the standard 95 is placed over the said standard so as to rest on the ill) trash hub er the plate 96, are. hermit-.11 bar as is pivotally mounted on the standard in the following manner: This bar is preferably in the form of a channel bar upon one end of which is bolted a hinge member 99 having a hole through which the standard passes, the hinge member resting on the upper end of the sleeve 97. A cap or nut 100 is screwed on the upper end of the standard to hold the bar thereon but permit the free swinging movementof the bar on the standard. The opposite end of the bar has a casting 101 bolted thereon, the outer end of which is yoke-shaped and is adapted to engage the upper portion of a standard 102, in the form of a tube which is secured at its lower end in the hub portion of a plate 103 which is secured to the table; this'standard being close to the frame A-B and diametrically opposite the standard 95. A cap 104 is screwed upon the upper end of the standard 102, and is adapted to engage or nearly Engage the yoke-shaped casting 101, when the bar 98 is in the position shown in Fig. 6, and thus cooperate with the cap 100 on the stand ard 05in holding the bar against upward movement. A bracket C is bolted to the bar 98, miduuiy of its length and this bracket comprises a body portion 105 having an up right bifurcated member 100 in the upper ends of which is pivotally mounted the cam portion 107 oil a vertically disposed lever 108. The cam portion 107, comprisesa hub 7 through which a pivot bolt 7 passes which also passes through the upper ends of the bifurcated member 106, a socket member 7 C to receive a handle, and the cam 7 which is in the form of twin parallel members which depend from the hub 7 and which are curved on their lower ends to provide cam surfaces.

These cam surfaces are adapted to engage the upper horizontal edges of twin projections 109 on an abutment member 110 having a square opening extending vertically through the same through which passes a square presser bar 111. to which the abutment member is adjustably secured by a set screw 112.

The presser bar 111 is slidably mounted in a corresponding guide-way 113 in the body 105 of the bracket G which is open on the side of the body next the swinging bar 98, so that the said swinging bar confines the presser bar in its guideway, as will be understood by reference to Fig. 8. A coil spring 114 surrounds the presser bar and is interposed between the under side of the abutment member 110 and the top of the body portion 105 of the bracket.

Upon the lower end of the presser bar 111 is secured the hub portion of a circular plate 115 which in turn is secured to a presser block 116 which is of thesame size and design as the extension bottoms or tops e1npla ed, that 6i extending about one half an inch beyond the circumferential edge of the ordinary or regular bottoms and tops.

When the lever108 is pulled forward, the

cam surfaces of'the members 7 D ride on the projections 109 of the abutment 110 and the presser block 116 is thereby forced down upon an extension bottom or top, as the case may be to clamp the same to the usual bottom and hold it under pressure during a complete rotation of the table, during which period the glue or other adhesive becomes set and the bottom or top is prevented from.

warping.

The die blocks 71 and .72 have secured thereon guides 117 of slight thickness which are adapted to center the extension top or bottom with respect to the block 70 when the extension is placed thereon, as will later appear.

The operation of forming-and clamping a box band, and securing thereto the regular bottom and then the extension bottom in connection with the improved machine above described, is as follows, the word extension being used as applicable to either the top or bottom of the box as the operation 'is the same in either c se. The bands F are out in lengths to exactly conform to the outline strip is preferably about an inch wider than the band and extends a half inch beyond each edge of the band. One edge portion of this strip is bent over the edge of the band and adhered to the inner face of the band but the other edge of the strip is left un folded as shown in Fig. 10 and the band is then ready to be placed on the forming block 70.

The meclulnism for rotating the table is set in motion and this mechanism can be governed. to intermittently move the table after such intervals that the'periods when the table is at rest will be of sufiicient duration 7 to enable the attendant to-perform the necessary work in the production of a box. The attendant first swings the bar 08 back to the position shown in any one of the mechanisms on the right side of Fig. '1,

so that the...

presser bloc-1:116 will be out of the way and sixteenth of an inch wider than the thickness of the block 70 so as to surround the bottom I as shown by Fig. 12. The attendant then swings the handle 68 inward whereby the dies or formers 71 and 72 are moved inward against the bandand clamp the same against the block 70 with a resilient pressure. The unfolded portion of the strip H is then folded down upon the bottom 1, thereby securing the bottom to the band. Glue is then. applied to the bottom I around the edge portionthereol' or to the extension J asmay be found mostpracticable, the extension J is placed upon the bottom I, the guides 11? centering it so that it will be concentric with the band 1*, but will extend a half inch beyondzthe same at all points.

The bar 98 is then swung to the position shown in Fig. (3, when thepresser block 116 will be above the extension 5 and a slight distance from it; the lever 108 is drawn upon and the presser block is forced down upon the extension J in the manner before described, and the said extension is thus clamped against the be bottom and so held until the table makes a complete rcdation during which time the glue has become set and this part of the box is completed. The operation is repeated until six half box s have been completed, when the table will have made a complete rotation, and the first half box oi? the series is ready to be removed.

The attendant then pushes on the lever 108 which releases the cams 7 and the presser block 116 is raised from the extension. by the spring 114:. The bar 98 is swung around so that the presser block will entirely uncover the extension J and the lever (38 is swung outward which permits the frames A and B together with the dies 71 and 72 to slide apart under the action of the springs 58 and 59 respectively.

The lever 91 is then drawn .upon to raise the plunger 75, in the manner previously described, and the plunger plate 92 is forced against the bottom I and pushes the half box off the block 70. A stop 118 limits the outwa rd movement of the lever 91.

The shaft 2-35 to which the table is secured, extends a suitable distance above the table, and a much smaller table 119 secured thereon. A circular plate 120 is secured to the table 119 having a. hub which registers with an axial hole in the table and the shatt passes through the hole in the table and through the hub on the plate 120 and a set screw 121 in the said hub is s irewed against hiding the said channel. bars as well as the supporting mechanism and thereby adding to the artistic appearance of the table.

In Fig. 13 is shown a modification of the band forming bloclt by means of which a box of less depth than the thickueiis oi? the said block can be made without any change in the dies or other parts of the mechanism. In this arrangement a. number of holes are bored into the block through its edge surface and into these holes are inserted thimbles 123 which are open on their inner ends, their outer ends being closed by a flange plate 124: having screw holes through which screws are passed which are screwed into the block thus holding the thimble in place, the flanges being flush with the surface of the block and each having a central hole. liefore placing the thin'ibles in the holes, coil springs 125 are placed in the holes, and metal plungers are placed. in the thimbles, "aid plungers having pins which project through the openings in the li plates 12%. The thimbles are then pres A holes in the block and secured by screw before stated, and the springs will. hear on the end walls of the holes in the block and on the ends of the plungers, so that the pins 126 will normally project through the holes in the flange plate 12-h Tn placing the box band around the blocl; T9 the bottom edge of said band will res upon the pins 126, and when the dies 71 and 72 are slid to engage the band and clamp it against the block, they will at the same time eng e the pins 126 which will be pushed in agail the action of their springs 125, thus offering no resistanc to the clamping action of the dies, The band cannot drop, as the pins when compressed will still project a distance equal to the thickness olfthe band and thus support the same.

By the former method the ordinary bottom was secured to the band by a narrow strip and then a. finishin strip wa: gluedv around the band over the first strip, and this finishing strip extended beyond the lower edge only or the band, and was tolded around this edge as in the present instance. But by making the strip wide enough to extend beyond each edge of the hand. one operation is entirely elii'niuated, as the finishiug strip, which projects beyond each edge of the band, serves to secure the regular bottom to the band, thus eliminating the narrow strip.
